Reset

On startup, releasing the ASIC reset is executed by EC_nRST through MPR.After releasing the ASIC, the local reset signal should be sent to CODEC by releasing the soft rest from MPR, and CODEC fac-tor should be downloaded from MPR.

Packs 2.048, 4.096, 8.192 MHz highway (Max.64 timeslot). (voice communication bus in the circuit board)The PCM data of arbitrary streams 0~15 (128 timeslot / 1 stream) on the CT bus can switch to the arbitrary local highway (64timeslot) by the local TSW.The timeslot configuration example of the local highway is shown below.Timeslots between slot 8 and slot 15 are used by the Sub Board.
